What AGSC Certification Means for the Person Working on Your Car
Auto glass installation is largely unregulated. Certification is the closest thing the industry has to a real standard.
Key Takeaways
- Most states do not license auto glass technicians at all
- AGSC certification tests against the industry safety standard
- The standard covers adhesives, cure times, pinch weld prep, and glass handling
- Ask whether the specific technician is certified, not just the company
An unregulated trade
In most states, no license is required to replace a windshield. Anyone with a cold knife and a caulk gun can advertise the service. Given that the windshield is a structural safety component, that is a genuine gap.
What certification actually tests
The Auto Glass Safety Council maintains the industry standard for replacement, and certification tests technicians against it: correct adhesive selection, published cure times, pinch weld preparation and corrosion treatment, glass handling, and retention system integrity.
Ask about the technician
A company can register with a council without every technician being certified. Ask whether the person actually coming to your car is certified. We can answer that by name before dispatch.
